SPECIFICATION forming* part Of Letters Patent O. 517,362, dated March 27, i894.

Application filed July l 1893. Serial No. 479.609. (No model.)

To all whom it may concern:

I Se it known that I, GEORGE B. PULLEY, a citizen of the United States, residing at Oleone, 1n the county of Multnomah and State of Oregon, have invented a new and useful Stump-Extractor, of which the following is a specification.

The invention relates to improvements in stump extractors.

The object of the present invention is to provlde a simple and inexpensive stump extractor, which will enable stumps to be readily pulled out of theV ground, and in which the gearing may be readily thrown out of mesh to enable the cable to be readily unwound.

A further object of the invention is to prevent such cable unwinding too rapidly and becoming tangled. i

Theinvention consists in the construction and novel combination and arrangement of parts hereinafter 4fully described, illustrated in the accompanying drawings yand pointed out in the claims hereto appended.

i In the drawings-Figure 1 is a side elevation of a stump puller constructed in accordance with this invention. view. l

Like numerals of reference indicate correspending parts in all the gures of the drawings.

1 designates a frame, provided with longitudinal runners 2 and supported by inclined end braces 3 and it and having journaled in it in suitable bearings a winding shaft 5 and a drum shaft 6, which are disposed vertically in the frame. The winding shaft is extended above the frame, and has secured to it av sweep lever 7, and the drum shaft carries a drum 8 and upper and lower cog wheels 9,

Which mesh with pinionsl 10 of the winding shaft 5, whereby a cable (not shown) is wound around the drum for pulling a stump out of Ithe ground. The cable (not shown) may be of steel wire, or of any other desired construction, and is designed to be provided with a suitable Vgrapple for engaging stumps, as will be readily understood. When such ca- -ble is unwound afterpulling a stump preparatory to the extracting of another one, the winding shaft, which is vertically movable in its bearings, is lifted sufficiently by a shift- Fig. 2 is a plan` ing lever l1 to carry the pinions 10 out of mesh wit-h the cog wheels 9, thereby leaving the drum free to rotate. The shifting lever is loosely connected, at a point intermediate of its ends, with the winding shaft 5 between upper and lower collars 12; its inner end is fulcrumed on a rod or bar 13, which depends y from the top of the frame; and its outer end is shaped into a handle, and is adapted to engage a supporting hook or catch 14: of a plate 15 to hold the winding shaft elevated to keep the gearing out of mesh. The rotation of the drum is regulated to prevent a cable from unwinding too rapidly and becoming tangled, by a brake composed of a brake-lever 16, which is fulcrumed at its lower end on one of the runners, and whichv has its upper end shaped into a handle, and a horizontal brakebar 17, which is pivoted at one end vto the frame, or rather to one of the runners thereof, and -it has its other end pivoted to a connecting bar 18, which extends to and ispivoted to the brake-lever'l. It will be seen that the stump-puller enables great force to be exerted in pulling a stump, and that the strain on the shafts, gearing, and the frame is equalized by locatingy the gear wheels at each end of the drum. It will also be apparent that the rotation of the drum, when the gear wheels vare out of mesh is controlled to prevent a cable unwinding too rapidly and becoming tangled.

Changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

What I claim is v 1. In a stump puller, the combination of a frame, a vertical drum mounted therein, cog wheels arranged at the ends ofthe drum, a vertically disposed winding shaft journaled in the frame and having a longitudinal movement, pinions mountedy on the winding shaft and arranged to mesh with the cog wheels, a

fulcrum bar depending from the frame, a supporting catch secured to the frame, and a shifting lever fulcrumed on the depending barand connected with the winding shaft and arranged to engage the catch, substantially as described.

2. In a stump puller, the combination of a frame, a vertically disposed drnm,cogwheels arranged at the ends of the drum, a longitudinally movable vertically disposed winding shaft jonrnaled in the frame, pinions mounted on the Winding shaft and arranged to mesh with the cog wheels, ashifting lever connected with and adapted to move the Windingshait` longitudinally, a brake-bar fulcrnmed on the frame and arranged to engage one of the cog wheels, a brake lever pivoted to the frame and connected with the brake-bar, and a sweep lever `secured to the Winding shaft, substan tially as described.

In testimony that I claim the foregoing as I5 my own I have hereto axed my signature in the presence of two Witnesses.

GEORGE B. PULLEY.
